Should I hold or sell my PSA 10 Mega Greninja ex #116?
My first PSA 10 just came back from PSA! The last sale I saw was around $350.
I also have other Pokémon cards from Chaos Rising and the 30th Anniversary worth around $75–$80 combined.
I wanna start trading my cards to work my way up to more valuable ones, but I’m not sure if trading my Greninja is the right choice. Would you hold it or trade/sell it? What would you do?
